SIX-WHEEL CAR-TRUCK CONSTRUCTION.

Application led February 10, 1927. Serial No. 167,279.

This invention relates to improvements in six wneel car truck constructions and contemplates side-iframes, each comprising equalizing end members and a. central equalizing member flexibly connected at its ends with inner end portions of the end members, said truck also comprising transverse bolsters mounted in side trames and connected by bridge bars, and a longitudinal bolster between the transverse holsters and having key connection therewith, said longitudinal` bolster also having lateral lugs to engage the transverse bolsters.

In the accompanying drawings,

Figure 1 is a side elevation ot a six wheel truck embodying the improvements;

Figure 2 is a partial plan View,

Figure 3 is a fragmentary sectional view, and

Figure 4 is a section on line 4 4 of Figure 2.

ln the drawings, only one side frame construction is shown but it will be understood that two such constructions are employed,

one at each side of the truck. The side trames each comprises three members; two equalizing end members 1 and 2 and intermediate or central equalizing member 3 with the ends of which latter the inner ends of the end members 1 and 2 are flexibly connectechhthe end members being so formed that their inner 4end portions will be disposed parallel with each other as shown in Figure 2 and connected respectively with the far ends of the central or equalizing member 3. rllhe inner end ot each end member 1 and 2 is contracted in width as at 4 and enters between upwardly projecting flanges 5 on the central member 3. A bolt 6 passes transversely through the flanges 5 and freely through a transverse hole 7 in the end member 1 (or 2).

Journal boxes 11 are secured by means of bolts 12 and plates 13 to the respective members of the side `frame as shown in Figure 1 and the central equalizing member is provided with an integral axle box construction 14. Each oit' the end members 1 and 2 of the side frame is provided with a bolster opening 15 which receivesthe end portion of a bolster 16, the latter being located at respective sides and spaced from the central axle 17, the latter being mounted in the axle boxes of the central or equalizing member 3 while the axles 18, 18 at the ends of the truck being mounted in the axle boxes secured to the end members 1-2 of the respective side trames. Spring seats 19-19 are located in the openings in the members 1 and 2 and inn terlockingly engaged with the latter as at 20. Between these seats and the transverse bolsters 16, springs 21 are disposed. Each of the spring seats 19 is provided with an inwardly projecting bracket 22 adapted for the reception and support ot a brake hanger, said brackets being located intermediate ot' the'wheels 23-24-25 Located upon and having interlocking connection with the ends of the members 1 and 2 which project over the axle boxes carried by said members, are

forwardly projecting brackets 26, the latter being secured in place by the same bolts which secure they axle boxes to said members 1 and 2. The outer ends of the brackets 26 are made to project inwardly and constitute brackets -for outer brake hangers.

The transverse holsters 16 are provided with lugs 27 which engage the inner sides of lthe side trame members 12 respectively and the outer projecting ends or the transverse holsters are connected adjacent each side frame by a bridge bar 28, the latter constituting guide means for the side frames and the transverse holsters and the latter having guides 29-30 for the bridge barto maintain proper alignment of the latter.

A longitudinal bolster 31 is disposed intermediate the transverse holsters and is provided at its respective vends with reduced portions 32 which enter the transverse bolster-s and said longitudinal bolster is formed with shoulders 33 to engage the transverse bolsters and maintain them in proper positions. The upper and lower portions of each transverse bolster are provided with aligning openings 34-35 and the longitudinal bolster is provided with an opening 36 which aligns with the openings 34-35 and through said openings a vertical pin or key 37 is passed and secured against displacement by means of a Cotter 38. By

thus keying the longitudinal bolster at the comprehended by copending application 22 Aca-r trucky comprising side i'raines,. two transversebolsters inonnted1 in the side trames, and a longitudinalbolster between the transverse holsters and having a. key connection at its end,l portions therewith, saidlongitiulinal` bolster having lugs to engage the transverse holster.
